In order to evaluate the effect of polyphosphonic acid used as a stabilizer on the hydrogen peroxide, VSP2 (Vent Sizing Package 2) was employed to carry out the thermal runaway reaction for the various concentrations of Amino Trimethylene Phosphonic Acid(ATMP) with hydrogen peroxide (H2O2) and H2O2 mixes with 100 ppm…
The widespread implementation of surface enhanced Raman scattering (SERS) techniques for chemical and biological detection requires an inexpensive, yet robust SERS substrate with high sensitivity and reproducibility. To that end, we present a facile method to fabricate plasmonic SERS substrates with well-distributed S…
Here we report a direct synthesis of a mesoporous TiO2-RuO2 composite. Titanium tetraisopropoxide (TTIP) and RuCl3 are used as inorganic precursors for TiO2 and RuO2, respectively. Evaporation-induced assembly of spherical micelles made of an asymmetric poly(styrene-b-2-vinyl pyridine-b-ethylene oxide) triblock copoly…
Abstract—In this paper, we propose to realize ultra-wide-band absorber (UWBA) based on anomalous refraction/reflection of phase gradient metasurfaces (PGM). To achieve high absorption and meanwhile keep small thickness at low frequencies, PGM is incorporated into conventional magnetic materials (MM). The absorptivity…
A small (sub 6 nm hydrodynamic diameter) and pH-responsive gold nanoparticle photothermal agent is reported.
BaCe 0.45 Zr 0.4 Y 0.15 O 3-δ (BCZY4015) was synthesized by a solid state reaction method and its charge and mass transport properties were analyzed. The solutions of analytical defect equations were obtained in terms of various defect concentrations to calculate the partial conductivity of various charge carriers. Th…
Proposed mechanism of nanoparticle formation at high concentration.
To enhance tumor magnetic resonance imaging (MRI) signals via the selective accumulation of contrast agents, we prepared folate-modified gadolinium-lipid-based nanoparticles as MRI contrast agents. Folate-modified nanoparticles were comprised of polyethylene glycol (PEG)-lipid, gadolinium diethylenetriamine pentaaceti…
This paper describes a process of obtaining nanosilver and nanogold based on chemical reduction using substances contained in the aqueous extract of dog rose (Rosa canina). The resulting products were subjected to spectrophotometric analysis (UV-Vis), and testing of the nanoparticles' size and suspension stability was…
Three-dimensional (3D) Co3O4–Ni3(VO4)2 heterostructured nanorods on nickel foam with excellent electrochemical behavior were synthesized by a facile strategy. A growth mechanism was proposed to explain the formation of the composite. The composite combined separately the advantages of the good rate capability of Co3O4…
Immiscible and miscible blends of poly(vinylidene fluoride) (PVDF) and acrylic rubber (ACM) were subjected to dynamic vulcanization to investigate the effect of crosslinking on phase separation. As a result of different processability, mixing torque behavior of miscible and immiscible blends was significantly differen…
The present paper aims at illustrating how end-attachment of water-soluble flexible chains bearing a terminal functional group onto graphene-like surfaces has to be carefully tuned to ensure the proper positioning of the functional moiety with respect to the anchoring surface. The model experimental system considered…
The hydrogen storage of Ti functionalized carbon nanocones and carbon nanocone sheets is investigated by using the state-of-the-art density functional theory calculations. The Ti atom prefers to bind at the hollow site of the hexagonal ring. The average adsorption energies corrected for dispersion forces are -0.54 and…
Ultrafine-grained materials show high strength at ambient temperature, high-speed superplastic deformation at elevated temperatures, and high corrosion resistance. Such materials have attracted increasing attention in the past twenty years. A number of severe plastic deformation techniques, such as equal-channel angul…
Ni–Cu spherical double hydroxide (SDH) was synthesized by a one-step, seedless and cost-effective chemical bath deposition method. It showed novel spherical morphology and an interesting composition, containing copper and nickel from elemental mapping. For comparison, when the substrates changed from a copper foam to…
Metal-mediated modification of soft spherical assemblies is reported <italic>via</italic> introduction of a coordinating linker for FF dipeptide. Single crystal data, microscopy and reversal of soft structure coalescence is described.
Tonpilz acoustic transducers for use underwater often include a stack of piezoelectric material pieces polarized along the length of the stack and having alternating polarity. The pieces are interspersed with electrodes, bonded together, and electrically connected in parallel. The stack is normally much shorter than a…
Mixed Au nanoparticles (NPs) with wide absorption spectra of 300–1000 nm and three absorption peaks of 520, 600, and 770 nm are assembled onto the ITO anode in polymer solar cells to significantly improve the power conversion efficiency and short-circuit current by factors of 24.2% and 18.6%.
In the last few years, there has been growing interest in employing metamaterials (MTMs) to enhance antenna gain. In this paper we proposed a novel structure of planar folded-line left-handed metamaterial (FL-LHM) and applied it to improve the gain of three 5.8 GHz microstrip antenna types: a circularly polarized patc…
A luminescent 5-connected galloborate with open-framework layers has been obtained under mild hydrothermal conditions by incorporating [GaB <sub>4</sub> O <sub>11</sub> (OH)] <sup>8−</sup> clusters.
